West Nile virus in Spain: Forecasting the geographical distribution of risky areas with an ecological niche modelling approach.
2021
West Nile virus (WNV), a well-known emerging vector-borne arbovirus with a zoonotic life cycle, represents a threat to both public and animal health. Transmitted by ornithophilic mosquitoes, its transmission is difficult to predict and even more difficult to prevent. The massive and unprecedented number of human cases and equid outbreaks in Spain during 2020 interpellates for new approaches. For the first time, we present an integrate analysis from a niche perspective to provide an insight to the situation of West Nile disease (WND) in Spain. Our modelling approach benefits from the combined use of global occurrence records of outbreaks of WND in equids and of its two alleged main vectors i…
Global phylogeography and geographical variation in warning coloration of the wood tiger moth (Parasemia plantaginis)
2015
Aim To investigate the phylogeography of the aposematic wood tiger moth (Parasemia plantaginis) across its Holarctic distribution and to explore how its genetic structure relates to geographical differences in hindwing warning coloration of males and females. Males have polymorphic hindwing coloration, while female hindwing coloration varies continuously, but no geographical analyses of coloration or genetic structure exist. Location The Holarctic. Methods We sequenced a fragment of the mitochondrial cytochrome c oxidase subunit I gene (COI) from 587 specimens. We also examined more current population structure by genotyping 569 specimens at 10 nuclear microsatellite loci. Species distribut…
Singing rate and female attraction in the pied flycatcher: an experiment
1990
«Attirer les femelles» est une des principales fonctions du chant des oiseaux. Beaucoup d'etudes ont mis en evidence l'effet de variations du repertoire sonore sur le succes d'accouplement mais peu d'entre elles sont consacrees a l'intensite du chant. Dans une telle optique, cette etude examine les effets de manipulations experimentales de chants sur la selection du partenaire par les femelles
Wydatki gmin na usługi opiekuńcze a zmiany demograficzne w Polsce

Local governments as the smallest units of territorial self‑government in Poland are responsible for providing care services. The growing number of the elderly can influence the expenditures level connected with ensuring proper care for them, and it may constitute a growing problem for local government, especially for districts with a lower level of socio‑economic development. In recent years, a quite high increase in benefits amount due to care services and specialist care services has been observed. Therefore, a question arises whether a significant dependence can be observed between the share of the elderly in the population and the degree of local governments’ financial burden due to pr…
To survive or succeed? : An analysis of biotechnology firms
2017
In this paper, we address the question whether there exists differences in the determinants that support survival versus success of small and medium-sized high-tech firms. We examine this question in the context of Finnish biotechnology industry by analyzing the survival of all dedicated biotechnology firms in the period of 1978–2008. We argue and show that the success and survival of firms are not necessarily driven by similar determinants. Specifically, we find that while the role of different types of alliances, focused market scope as well as legitimacy of the industry seem to be important both ensuring in survival and enhancing successful performance, determinants related to sources of…
Institutional distance and international networking
2017
We focus on how small- and medium-sized enterprises (SMEs) adapt to differences in institutional logics (values, beliefs, and rules) in their networking when they enter an institutionally distant market. We address gaps in the literature, relating to the role of institutional logics in SME internationalization, and how institutional distance affects the formation of network ties. We show how the social interaction involved in internationalization is embedded in the institutional logics followed by partnering actors. Specifically, we demonstrate how institutional distance may constrain the networking activities of SMEs and identify practices that may support successful internationalization. …
Il dovere di riservatezza dei dipendenti delle organizzazioni internazionali
2021
Apesar das diferenças estruturais e regulatórias que caracterizam as organizações internacionais individuais, a doutrina de hoje é unânime em afirmar a capacidade de cada organização de criar seu próprio sistema jurídico interno. A relação de trabalho dentro dessas organizações reproduz claramente muitas das características da relação de trabalho internas a um Estado e, embora haja uma falta de regras internacionais uniformes sobre o emprego, e cada organização internacional tenha absoluta autonomia jurídica e administrativa, é possível identificar certas obrigações e direitos dos funcionários internacionais que se replicam, de forma ampla e homogênea, na maioria das organizações. O artigo …
La Sábana Santa y sus implicaciones histórico-artísticas

RESUMEN DE LA TESIS DOCTORAL EN HISTORIA DEL ARTE “LA SÁBANA SANTA Y SUS IMPLICACIONES HISTÓRICO-ARTÍSTICAS” Realizada por Jorge-Manuel Rodríguez Almenar y dirigida por el Dr. D. Rafael García Mahíques Primera parte: LA SÍNDONE DE TURÍN La primera parte tiene la finalidad de conocer el objeto material sobre el que se ha construido la investigación subsiguiente: la llamada “Sábana Santa o Síndone de Turín”. Sin una base mínima de conocimientos no se puede entender el porqué del trabajo desarrollado posteriormente en las partes segunda y tercera. Sección I: Descripción de la Síndone. Siguiendo la metodología científica, lo primero que haré es describir materialmente el objeto. Y eso supone di…
Mācīšanās rezultātu nozīme profesionālās vidējās izglītības vadībā
2014
ANOTĀCIJA Promocijas darba „Mācīšanās rezultātu nozīme profesionālās vidējās izglītības vadībā” mērķis ir izpētīt mācīšanās rezultātu nozīmi profesionālajā vidējā izglītībā un noskaidrot, kā notiek pāreja uz mācīšanās rezultātos balstītu izglītības procesu. Pētījuma ietvaros tika veikta profesionālās izglītības iestāžu audzēkņu aptauja, skolotāju un darba devēju intervijas. Pētījumā secināts, ka skolotāji un darba devēji neizprot mācīšanās rezultātu lomu profesionālajā izglītībā. Skaidri formulēti mācīšanās rezultāti profesionālās izglītības programmās sniedz precīzu informāciju par mācību procesu un tā iznākumu visām iesaistītajām pusēm, līdz ar to vairāk jauniešu var izvēlēties profesionā…
Dynamique induite par champ laser femtoseconde intense : alignement moléculaire en milieu gazeux dense et effet Kerr
2011
This thesis is devoted to the study of dynamics induced by intense femtoseconds lasers pulses. The first studied dynamics deals with molecular alignment of CO2-X mixtures (X=CO2, Ar, N2), in dense gases (up to 20 bar). Up to now, this regime has never been studied experimentally. In the field-free regime (after laser/matter interaction), molecular alignment exhibits two components : a permanent alignment and a transient one. The influence of collisions appears through population transfers between rotational states, which leads to a decrease of these two contributions. Permanent alignment relaxation time is only tied to inelastics collisions whereas transient alignment relaxation time is tie…
